My point was that if we look at Rails performance going up 10%, what does that mean for time spent in Ruby. I'd believe anything from a 15% to a 80% reduction of time spent in Ruby code

I haven't seen 80% anywhere in the linked article[0] so let's use facts and not beliefs.

It is possible Ruby itself got accelerated a lot, okay, I am just not sure that's relevant since almost all Ruby usage is Rails.
